Step-by-step explanation:
Hey store buys a jacket for $20 then sells it to customers for 80% more than what is the selling price of the jacket
Given:
Cost of a jacket = $20
Then sells it to customers for 80% more than.
To find:
The selling price of the jacket
Solution:
We have,
Cost of a jacket = $20
Selling price = cost + 80% of cost
= [tex]20+\dfrac{80}{100}\times 20[/tex]
= [tex]20+\dfrac{8}{1}\times 2[/tex]
= [tex]20+16[/tex]
= [tex]36[/tex]
Therefore, the selling price of the jacket is $20.

Write an exponential function in the form y=ab^x that goes through points (0, 18)and (3, 6174)
Answer:
[tex]y = 18 \times {7}^{x} [/tex]
Step-by-step explanation:
Using the formula for exponential function,
[tex]y = ab {}^{x} [/tex]
Let plug in 0,18.
[tex]18 = ab {}^{0} [/tex]
Using the zero power rule,
[tex]b {}^{0} = 1[/tex]
[tex]18 = a \times 1[/tex]
[tex]a = 18[/tex]
Since a equal 18 let plug in what we know so far
[tex]y = {18b}^{x} [/tex]
Now let find b.
Let use the other point, 3,6174
[tex]6174 = {18b}^{3} [/tex]
Divide 18 by both sides and we get
[tex]343 = b {}^{3} [/tex]
Take the 3rd root of 343
[tex] \sqrt[3]{343} = b = 7[/tex]
b=7
The equation is
[tex]y = 18 \times 7 {}^{x} [/tex]

3 A small photograph has a width of 4 cm and a length of 6 cm
Dean enlarges the small photograph
The enlarged photograph has a length of 21 cm
Work out the width of the enlarged photograph
Answer:
14 cm
Step-by-step explanation:
Given that the width is 4 cm and the length is 6cm. If after enlargement, the length becomes 21 cm, the multiplier or factor of enlargement x may be computed as
6 * x = 21
Divide both sides by 6
x = 21/6
= 7/2 = 3.5
Hence increasing the width by the same factor, the width of the enlarged photograph will be
= 3.5 * 4 cm
= 14 cm

Hailey took a taxi from her house to the airport. The taxi company charged a pick-up fee of $2.40 plus $4.50 per mile. The total fare was $87.90, not including the tip. Write and solve an equation which can be used to determine mm, the number of miles in the taxi ride.
Answer:
The taxi drove Hailey for 19 miles.
Step-by-step explanation:
1. Subtract the tip.
$87.90 - $2.40 = $85.5
2. Divide by the price per mile. ($4.50)
$85.5 / $4.50 = 19

what 2 numbers multiply to -63 and add to-2
Two numbers are 7 and -9, so their product is -63 and sum is -2.
An equation is a mathematical statement that shows that two mathematical expressions are equal.
Let two numbers are x and y
Given,
The multiplication of 2 numbers is -63
[tex]x\times y =-63[/tex]
The addition of 2 numbers is -2
[tex]x+y =-2[/tex]
[tex]x=-2-y[/tex]
On substituting x in [tex]x\times y =-63[/tex]
[tex](-2-y)y=-63[/tex]
[tex]-2y-y^2=-63[/tex]
[tex]y^{2} +2y-63=0[/tex]
[tex](y-7)(y+9)=0[/tex]
[tex]y=7\\y=-9[/tex]
[tex]x=-2-y\\[/tex]
At y=7
x=-9
At x=-9
y=7
Thus, two numbers are 7 and -9
